Much of  this  framework already  existed  but was consolidated in the  1950s  when
planned shopping centres were added to several levels of the hierarchy. It has been estimated
that in larger cities (over 250,000) 36.8 per cent of  retail  provision is found outside the
central area; this proportion is inversely related to city size and is 55.3 per cent for cities in
the 40,000 to 49,000 range.
Retail trade has experienced considerable structural change since 1945. There have
been  upheavals  in  the  methods  and  organisation of  retailing,  a  blurring  of  the  retailing/
wholesaling distinction, escalation of multiples, an increase in store size, and greater bulk
buying by consumers. These changes adversely affected small stores and between 1950 and
1966 the number of general stores fell by 56.2 per cent and of grocery retailers by 16.3 per
cent. In part this trend was related to out-migration and the subsequent decline of the ‘corner-
shops’, but it can also be tied to economies of scale and the changing organisation of retailing.
Already by the early 1970s, four organisations together operated nearly 4,500 grocery shops
and accounted for nearly 22 per cent of sales. There is some evidence for a renewed role for
small convenience stores in suburban locations. Large-scale retail organisations have sought
to develop large out-of-town sites, although in the late 1970s only Brent Cross in suburban
north London could be described as ‘out-of-town’.
By the late 1980s, three ‘waves’ of retail decentralisation had been recognised. The
first wave involved the emergence of superstores and hypermarkets during the period 1964
to 1975. A second wave between 1975 and 1985 was composed of retail warehouses, retail
warehouse parks and retail parks; the Enterprise Zones at Swansea and Dudley were typical
of this type  of development. The initial sales emphasis  was on DIY  products, furniture,
carpets  and  electrical  goods  but expanded to  include  clothing,  footwear,  toys  and  car
accessories. The third wave dates from 1984 and the proposal by Marks and Spencer to
open out-of-town stores. This type of decentralisation affected the outlets for quality goods
and involved firms such as Habitat, Laura Ashley and World of Leather. Gateshead’s Metro
Centre, opened in an Enterprise Zone in 1986, was the first major example of an integrated
regional shopping and leisure complex. Following Metro Centre with its 136,430 square
metres  of  floor  space,  were  Merry  Hill,  Dudley (143,000  square  metres),  Meadowhall,
Sheffield (116,250 square metres) and the Lakeside Centre at Thurrock (116,250 square
metres),  with  other  planned  developments in  London,  Leeds,  Manchester  and  Glasgow
(Figure 10.3). The idea of a fourth wave in the 1990s focuses on the conflation of retailing
with leisure tourism, with the emergence of outlet malls or shopping villages, such as the
Clarks’ Village  at  Street  in  Somerset,  the  shopping  villages  at  Bicester, Oxford  and  at
Swindon. Other additions are the informal car-boot sales, new convenience chains, and the
emergence  of  tele-shopping  which  may  have  wider  implications  for  the  geography  of
retailing. There is now much greater diversity in the provision of retail sales and consumer
choices are changing accordingly.
Objections to out-of-town centres stemmed from fears of their impact on city-centre
trade  but the  earlier  hypermarkets  affected smaller  branches  of  multiples  rather  than
independent corner  stores  and  many  retailing  firms retained city-centre stores. There is
some force to the concept of the disadvantaged consumer but empirical evidence is equivocal.
Mobility is unevenly available but there has been an expansion of convenience stores, discount
stores and shopping transport, to offset the effects of out-of-town centres.
Overall, retail provision has responded to the two basic needs of redeveloping outworn
parts of the central city and adding new facilities to rapidly growing suburbs. Both of these
